I have an 05 lly and it is my first Diesel, so I'm not sure if it is normal to be able to hear the turbo spin down at shut down. I put a Banks Big Hoss kit on it with a K&N FIPK instead of the ram air from Banks. The ram air pick up from under the bumper and does not work so well with a snow plow.
Thanks
